The simulation study shows that linear polarization sensitivity of silvered orthogonal twin mirrors is better than that of aluminum or aurum mirrors at the range of 0.4μm~10μm, and the silvered orthogonal twin mirrors have less influence on polarization ratio than those of aluminum and aurum mirrors.
模拟计算结果显示:在0.4μm~10μm波段内,非理想正交镀银反射镜的线偏振灵敏度优于铝、金等正交反射镜,且对光束偏振度的改变最小,因此正交镀银反射镜在高精度偏振遥感探测中值得广泛应用;若把角度误差控制在0.5°内,则正交镀银反射镜的偏振特性对偏振遥感器的辐射度和偏振度影响很小,具有较好的消偏性能。

The main work can be summed up as follows: Firstly, we studied the thermal-field properties of VCSELs, and analyzed the influences of current spreading, material parameters and operating conditions on the temperature distributions. Secondly, we began with the electrode voltage and calculated the equipotential s distributions, compared the distributions of voltages and current densities in different depths of VCSELs, and then studied the influences of the oxide-confining region with different position or thickness, and the different sizes of the gain-guided aperture and emitting window on the distributions of the injected current density, carrier concentration and temperature in the active region. Thirdly, we realized the coupling of electricity, optical and thermal-fields, worked out the threshold voltage, calculated the distributions of the injected current density, carrier concentration and temperature under different offset voltages, and analyzed the impacts of temperature profile and carrier density on the refractive index, Fermi levels and optical-field. Finally, we gave the equipotential line distributions with considering N-DBR and double oxidized-confining regions, and analyzed theinfluences of N-DBR and double oxide-confining regions on the distributions of the current density, carrier concentration, temperature and optical-field.

The light emitted from a Keplerian ring around the objects with strong gravitational field should be affected by Doppler shift, gravitational redshift and deflection of light. The line profiles for a faraway observer are dominated by these effects. In this paper the precise solutions of line profiles for the Keplerian rings in the Schwarz-schild case have been obtained by means of the kinetic equation for photons.
